From 110V or 220V? Really?

I rather think that it's designed for *very* rich people, that want to have fancy gadget, looking like regular wall socket, but suckable to glass. To have something fancy to show to your colleagues at 74th floor of your exclusive office - 2 min of being "awesome" for a hundred of dollars, or so. No practical usage, whatsoever.

... and during those 11+ hours the building (or at least the window) should turn around to track the sun or the peak efficiency goes byebye.

Besides, let's suppose this miracle charger really works. Would you trust leaving it hanging on a window by a suction cup?
All it takes is one fall from 1-2 m height and you could bid adieu to the solar cell polycrystal.

what about plain portable chargers? are they reliable?
something like this (although that design might not be good for the n900s usb port)
